Hi,
I'd like to turn off all power to USB ports when the computer is off.
Right now it's on because I see lights coming out of USB wireless keyboard adapter.

I searched for ErP/Eup in the bios but haven't found anything. The only thing I could find in the manual is that the motherboard has "EuP Ready" printed on it.

Any help would be appreciated.

Buy a multiport USB wall charger like THESE, I got a 4 port Kensington at Walmart for under $20 and it keeps all the phones and stuff charged without concern for the computer status.

I can read, no problem. Sometimes there is a better solution than just solving the one initially brought up, Sure, turn off the USB ports if possible, but also think that there can be a better way to keep your devices charged.

ErP/Eup requires both a compliant motherboard (which have been around a long time), but also requires an ErP/Eup compliant power supply. My guess is that his PSU is not compliant. According to Intel "the EuP ready power supply must meet the standard of
5v standby power efficiency is higher than 50% under 100 mA current consumption."

Baloobab, check your PSU for compliance, as I would expect that is your issue. Then look at the wall charger units so that your devices will always be ready to go.

Here's a link to the manual:

Any other ideas what it's called?

Also check your PSU, as it must also comply to allow the motherboard to actually enable ErP/Eup. Motherboards have been compliant for a long time, many PSUs are still not compliant.
